one (especially because creating a wxFileConfig object might be a time
consuming operation). In this case, you may create this global config object
in the very start of the program and {\it Set()} it as the default. Then, from
-anywhere in your program, you may access it using the {\it Get()} function. Of
-course, you should delete it on the program termination (otherwise, not only a
-memory leak will result, but even more importantly the changes won't be
-written back!).

As it happens, you may even further simplify the procedure described above:
you may forget about calling {\it Set()}. When {\it Get()} is called and there

bool} you can work with function taking/returning {\it long} and just use the
casts. Better yet, just use {\it long} for all variables which you're going to

Although this feature is very useful, it may be annoying if you read a value
